New PTA-2 test machine

MDM is finally pleased to announce the launch of a new testing unit on the market.
A new concept of machine has been developed to check the quality of abrasive cutting discs.

What distinguishes it from past models is that on MDM PTA-2, the cut-off disc is driven directly by a brushless electrical motor and no longer by a commercial angle grinder.

 

Main advantages:
– Possibility to set any required testing speeds according to Customer needs.
– No more errors or differences which may depend on the use of a grinder brand rather than another one.

In other words, the new PTA-2 offers the most precise and objective results on the performance of your cut-off disc!

The machine cycle is conceived to reproduce a certain number of cuts always in the same conditions and on the same material.
Once the test is over, the operator will be able to obtain all necessary information about wheel wearing.
Data are downloadable on USB supports or directly on the Customer Intranet System.
Wheels testable range is between diameter 100 to 255 mm.
The machine is located into a safety chamber equipped with many connections for air dust.
This test is driven by Siemens PLC Simatic 1500.

FOCUS ON MATERNINI TESTING MACHINE

MDM Sales team is proud to present the full range of testing machines.
Aim of these units is to provide the end-user with detailed information regarding the performance of their cut-off or grinding wheels, both resinoid bonded or vitrified/ceramic products.
Smart and “easy-use” reports can be downloaded from the machines in order to have the best comparability between each kind of test. The mechanical precision of this equipment joined to a top quality accuracy of instruments guarantees a top-class laboratory for the examination of abrasive tools.

 

Let us start our presentation from the most common but useful test: burst/speed. Standard version of this tester runs up to 32000 rpm but, in case of specific technical requirements, MDM is able to provide even machines with higher or lower speeds. The operator inside the burst chamber fixes the wheels, starts the machine and that’s it! The machine detects the breaking point and the reached speed. A series of extra-safeties assures the correct running. About vitrified and ceramic wheels, special designs of the machine according to size of wheels to be tested is offered to the buyer.

 

 

Performance of abrasive discs: cut-off and grinding machines! The first one, called PTA, is a tester able to record all data concerning level and wear rate of wheels after a selected number of cuts. Concerning the control of grinding action of discs, PSA unit is the ideal instrument. An operator who leads these machines has the opportunity to set the test according to different variables like pressure of the grinders, current consumption, constant speed, different working axis setting etc.

 

 

A dedicated chapter belongs to balancing units. This variable is more and more determinant in order to give quality and reliability to every kind of abrasive disc. MDM machines check the balance or unbalance of wheels thanks to a dedicated software able to provide both the value and the positioning on the surface of the unbalanced disc. This family of testers covers all the measures of cut-off and grinding wheels present in the market: from 100 up to 600 mm (4” to 24”) with thickness up to 8 mm (0,3”).

 

Last but not the least, the speed tester dedicated to complying of safety rules UNI EN 12413:2011. This is the three sides loading where tests are settled as the norm says. Machine is available both in full automatic and manual version.

Do not forget the opportunity to create a dedicated lab composed by two of the above-described testers, which are lead by a common interface. In this way, only one operator is fully engaged in the control and develop of the abrasive tools.

This is just a short description of Maternini testing machinery and their main features.
